This invention" relates to seed-planting machines and has 7 for 'its'i'ob jectf to 7 provide improved means for adjustablyseoflring a air of rsarwardly-diverging V ffirro'W open- 16 mg devios'alongside of and connected with the, usual'curvedrrunner and hollow shank thereh1 making provision for readily chang ng the spacing apart of suchdevices soasltorary the Width of furrows as desired 'fT- his object I attain by the means shown in the drawings and hereinafter par ticularly described. That which lbe'live to be novel will be set forth in the claims.

12' iiidicatestwo similar bars arranged opposite'each other and supported against opposite sides the said shank 10 and its runner 1'1; each of said bars havingedjustablysect'ird toit; as hereinafter more par-' ticularlyi descrihefi, one of the said inshiied disks. Theforward portions of thesehsrs lie alongside ofthe upturned'forward portion Of illfjlllfilifiif and are firmly clamped to such riinii'eLr-Y As shown such clamping 'is' effected hyf'afbolt 13' that passes through the endpp'rfiofis of the bars that project beyonditlfe runner and by a bolt 14 that passesthr'ongh the bars and draws them closely'togetlier" at a point some little distancein rear of the inner or rear edge of the runiir; In rear of the bolt 14 the bars'arerespsctively bent ontwardto provide two straight and rather sharply divsrging portions, indicated by 15, and are then bent ii'iwardly' toward each other to form two curvdportions, indicatedby 16. The ends of'thesercnrved plortions 16 bear against opposite sides 0ft e shank 1O. 17' indicates abolt'passing through the bars 12m substantially that pointwhere they are'farthest apart being approximately at the point where'the portions 15 and 16 of each bar mergiinto each other. By tightening the not on this bolt 1? the rear ends of" the curved portions 16 of the bars will be forced and'heId ver-y firmly against thesides of t e S a k."

lS iiidibatst gVo disks carried by the bars l2'resf ectii efmisach disk being rotatably secured to 9, hollow cylindrical boss 19 madman-a block 20 which is movably attached tothe outer face of the diagonal portion 15 0i one of the bars 12. As shown, the disk'hasafsmall plate 21 attached centrally of its outer face, with which is formed an elongated hub 21' that projects through the disk and" is jur'naled in the 19, being ecured therein by a bolt the nut therefor bein located ih'arecess in the innei' faoe of iilfe%lock, as shown; A collar 23 oi'fthe inner face of the plate'EZl surrounds the outer end of the boss. By the" construction briefly outlined each disk willhe'rotatably connected with its block 20.

Each of such blocks fits against the outer face of its bar 12 and is aided in being held thereon by flanges formed at its sides that overlie the edges of the bar, and each block independently adjustable along the portion 15 of its bar. As shown, it is secured in different adjusted positions by means of a bolt 24 passing through the block and through any one of a series of holes 25 in the bar, but, obviously, instead of such series of holes a slot may be provided.

By my invention two ground-opening implements, such as the pair of disks in the construction shown, can be readily applied at opposite sides of the shank and runner of an ordinary planter when the same are needed or desired. In so applying them it will only be necessary to remove the bolt 13 and loosen the bolt 14 sulliciently to allow the forward portions of the bars 12 to be pushed into place at opposite sides of the upper part of the runner. At the same timeand w th the bolt 17 loosened somewhat the curved rear ends of the bars will be placed in position against the sides of the shank. Thereafter a tightening of the three bolts 13, 14, and 17 by a turning of their respective nuts will tend to draw the bars together and clamp between them very firmly the runner and shank. It will be noted that with the parts arranged as shown the forward bolt 13 will come in contact with the front curved edge of the runner; this location is of advantage in that it tends to counteract any tendency of the disks to rise due to their pressure against the earth when the planter is in operation. I prefer to provide, as shown, a plurality of holes in the forward portions of the bars for the reception of the bolt 13, as provision is thereby made for better adapting the bars to different shapes and makes of runners and also permitting the bolt 13 to be located in contact with the runners forward edge when the disks are clamped in a lower position than shown in Fig. 1, for it is to be borne in mind that by reason of the novel attaching means shown and described the disks can at any time, and with but very little trouble, be adjusted up and down on the shank and runner, or with respect to either the shank or runner, to regulate the depth of furrow.

By reason of the adjustability of the blocks 20 along the diagonal portions 15 of the bars, the dlsks can be set farther from or closer to each other to make a furrow of the desired width.

The fact that only one bolt needs to be entirely removed when applying the pair of disks to or removing them from a machine is of very considerable advantage in that the two bars and their respective disks may at all times be kept together by the other bolts, and consequently the two bars and their disks will be considered and handled as a single attachment.

What I claim as my invention and desire to secure by Letters Patent, is

1. In a planter, the combination with a hollow shank for the passage of seed, a runner extending from said shank and provided with an upturned l'orward end portion, a pair of bars secured against opposite sides of said shank and upturned end portion and bridging the space between said parts, each of said bars having a rearwardly-inclined portion, blocks slidingly secured upon such inclined portions, and a disk rotatably mounted upon each block.

The combination with the shank and runner of a planter, of two bars extending between sald parts and secured respectively against opposite sides of the shank and runner, said bars diverging rearwardly from a point in rear of the upper part of the runner, and a ground-opening device mounted upon the diverging portion of each bar.

3. The combination with the shank and runner of a planter, of two bars extending between said parts and secured respectively against opposite sides of the shank and runner, said bars diverging rearwardly from a point in rear of the upper part of the runner, and a ground-opening device mounted upon the diverging portion of each bar, said groundopening device being movable longi- ItJudinaHy of such diverging portions of the ars.

at. The combination with the shank and runner of a planter, of two bars each com prising a substantially straight portion at one end, an intermediate outwardly-inclined portion and an inwardly-turned portion at its other end, means for securing the firstnamed portions of the bars against opposite sides 0 said runner and securing the second-named end portions against opposite sides of said shank, and a ground-opening device connected with the said intermediate portion of each bar.

5. The combination with the shank and runner of a planter, of two bars each comprising a substantially straight portion at one end, an intermediate outwardly-inclined portion and an inwardly-turned portion at its other end, means for drawing said bars toward each other to cause them to clamp between them at their said end portions respectively the said runner and shank, and a ground-opening device connected with the said intermediate portion of each bar.

6. The combination with the shank and runner of a planter, of two bars each comprising a substantially straight portion at one end, an intermediate outwardly-inclined portion and an inwardly turned portion at its other end, means for drawing said bars toward each other to cause them to clamp between them at their said end portions respectively the said runner and shank, and a ground-opening device connected With the said intermediate portion of each bar, said ground-opening devices being movable longitudinally of such intermediate portions.

7. The combination with the shank and runner of a planter, of two bars each C0111 prising a substantially straight portion at one end, an intermediate outwardly-inclined portion and an inwardly-turned portion at its other end, means for drawing said hats toward each other to cause them to clamp between them at their said end portions respectively the said runner and shank, and a ground-opening device connected with the said intermediate portion of each bar, said means for drawing the bars together comprising a plurality of bolts, ihe forward one of which lies adjacent to the front edge of the runner.
